Toilet in the dining room

This is a dream from a coworker, DK.

Against the wall in their dining room was a toilet. It was normal for people to use it while other people were eating, but it was understood that you simply ignore the person while they are on the toilet. They had a boy visiting who did not know the rules, and when DK used the toilet, he stared at her. She yelled that he should not be staring.

The boy was someone DK knew in real life and for no reason other than the dream, she disliked him from that day on.
